3.11. Wrap Up

This lesson is meant to be a stopping point to check students' understanding of the material covered thus far, before proceeding to the next unit.

Each unit wrap up will provide App Inventor drills that would be appropriate for the material covered in the unit. As an instructor, you also have the option to give a unit quiz to your students.

3.11.1. App Inventor Drills

For this unit, there are three sets of coding drills linked to the Wrap-up Unit on the student-facing site. These can be assigned as additional exercises to help improve coding knowledge and skills. Note: Solutions are only available to verified educators that have joined the Teaching Mobile CSP Google group/forum in Unit 1.

  • Setters, Getters, and Math -- drills that use App Inventor's variable and setter and getter blocks together with simple math operations from the Math drawer. (Solutions)
  • If/Else Drills -- coding drills that focus on if/else statements and logic. (Solutions)
  • Code Refactoring -- exercises that focus on revising and existing to incorporate procedural abstraction by defining procedures and functions. (Solutions)

3.11.2. Unit Assessments

AP Classroom

Please review College Board's guidelines for the use of topic questions in AP Classroom (detailed in Teach 1.16).

The following are the suggested topics that you could assign once students have completed this unit. (Note Before adding questions to their formative assessment, teachers should review the questions in each topic to ensure that the questions are appropriate for their students depending on what was covered in this unit. It is not necessary to assign all of the questions.)

Suggested Topics:

  • Topic 1.4 Identifying and Correcting Errors (excluding procedures with parameters)
  • Topic 2.2 Data Compression
  • Topic 2.3 Extracting Data from Information 
  • Topic 3.1 Variables and Assignments
  • Topic 3.2 Data Abstraction (excluding multiple lists)
  • Topic 3.3 Mathematical Expressions
  • Topic 3.4 Strings
  • Topic 3.5 Boolean Expressions
  • Topic 3.10 Lists (excluding loops with lists)

Mobile CSP Assessments

Mobile CSP has created an assessment bank of questions that can be used for each unit and at the end of the course. This assessment bank is designed to be made ONLY available to teachers and not to students, except when administering the assessment. A tool to create your own assessments from a spreadsheet is available, but requires an understanding of scripts in Google Sheets. Assessments are only available to verified educators who have joined the Teaching Mobile CSP Google group/forum in Unit 1. Alternatively, you can access a Google Doc and Form version of the assessments using these links:

Many of the Mobile CSP teachers from previous years have decided to quiz students in between the larger exams (midterm and final). Some of those teachers have shared their quizzes. The Mobile CSP Assessments Repository contains copies of those quizzes (most of which were made with Google Forms) and instructions for how to use those quizzes.
